Vis Island
Green Cave on island Ravnik reflects stunning emerald light through a hole in its ceiling — a must-see near Vis.

Green Cave is located on a small island Ravnik on the south side of island Vis. Through a small hole in the ceiling of the cave sunlight comes in and reflects a green color inside the cave.
The cave has two large entrances and is operated by Port Authority. It is necessary to buy tickets to enter the cave.
Sunlight pours through a hole in the cave ceiling, turning the still water a luminous shade of green.
You can swim and snorkel right inside the cavern — bring a mask to enjoy the glowing water.
Just off the islet of Ravnik near Vis; the wide entrance lets boats slip straight in.
Midday sun gives the strongest green glow; it's quieter early in the morning or late afternoon.
